  Exploit (computer security) - Wikipedia, the free encyclopedia
In computer security, an exploit is a piece of software that takes advantage of a bug, glitch or vulnerability in order to gain control of a computer system or allow privilege escalation or a denial of service attack.
Exploits against client applications may also require some interaction with the user and thus may be used in combination with social engineering methods.
Such exploits are referred to as 'zero day exploits' and to obtain access to such exploits is the primary desire of unskilled malicious attackers, often nicknamed script kiddies.

 Computer Viruses [encyclopedia]   (Site not responding. Last check: 2007-11-05)
In computer science a virus is a piece of program code that, like a biological virus, makes copies of itself and spreads by attaching itself to a host, often damaging the host in the process.
The host is another computer program, often a computer operating system, which then infects the applications that are transferred to other computers.
A small percentage of viruses are the result of computer code that operates in an unexpected manner, but the majority of viruses are programs deliberately written to interfere with, or damage, other programs or computer systems.
